Lubos Mitas

Bio

Professor Mitas joined the NC State Department of Physics after spending several years as a theorist at the National Center for Supercomputing Applications, University of Illinois. He is a member of the Center for High Performance Simulation specializing in computational and theoretical approaches for nanoscience/materials, biomolecular and quantum systems. His work includes many-body computational methods such as quantum Monte Carlo simulations of electronic structures. He is known for pioneering high-accuracy calculations of atoms, molecules, clusters and solids, analysis of many body nodes of fermion states and applications of pairing wave functions to electronic structures. He has also been co-developer of multi- dimensional spatial interpolation and landscape processes methods for modeling, visualization and simulations of geospatial processes.
